Being CGA, it was limited in colors, but being basically Pac-man, it didn't need many, and it made copious use of what was available. A green wire frame of walls on a blue background, basic stats to the right in orange and green text, and a mini-map giving you radar locations of the ghosts. These ghosts are themselves red, green, changing if you eat a big dot.

There wasn't a lot to this game, any more than there was to Pac-man. But it was 3D, which in addition to being fairly novel for the early 80s, made the maze a little mazier (until you pulled up the map). It wasn't complicated, but it added a small level of difficulty and, for lack of a better word, spookiness. Those ghosts bore down on you in three-dimensions.
